Hitachi's 500GB Touro Mobile Pro portable USB 3.0 hard drive is unashamedly modelled after the Apple iPhone 4. It looks so much like one that you could probably play a joke on your friends with it from a distance. Once they realise that it's a little bigger than an iPhone 4 and that it doesn't actually have a screen, hilarity may ensue. We only got polite laughs when we tried it, but we're adamant that someone with suitable comedic skills could pull a few legitimate laughs with it.

Anyway, where were we... oh yes, it's a hard drive, not an iPhone 4. There is not much to this drive: it has a USB 3.0 interface on its bottom end, Hitachi branding on the front and a sticker with its model number on the rear. A blue status light illuminates once you plug the drive in to your computer using the thick, but ultimately too short USB 3.0 cable that ships with it. The cable is only around 40cm long and hard to manoeuvre. The drive doesn't require a separate power connection - it gets all its power from the USB port.

On the inside, the Touro Pro has a 500GB hard drive with a spin speed of 7200rpm. It has a formatted capacity of 465GB, which, considering the drive's price of £54, equates to a cost per gigabyte of 11.6p. This is cheaper than similar USB 3.0 portable drives we've seen, such as the Iomega eGo.

Hitachi Backup software

The reason for the Touro drive's Pro designation is to do with the backup software that Hitachi ships with the drive, which is called, funnily enough, Hitachi Backup. This software is present on the drive itself and it's available for both Windows and Mac users.

The software is very basic and it's set to back up everything in your user account folder by default (although you can specify which folders should be backed up, too). To start backing up your data, all you have to do is make sure the Hitachi is selected as the back-up location and flip the software's 'on switch'.

Once the back up process is switched on, it will start backing up all your files immediately in the background while you work. The time it takes to back up your data will depend on the amount of data and the type of data (small or large files) you have in the folder that you're backing up.

Rest assured, though, however much data you have, backing it up via USB 3.0 is a lot faster than backing it up via USB 2.0. If your computer has a USB 3.0 port, then the Hitachi is well recommended. In our test scenario using a typical laptop with a 7,200rpm hard drive installed, the drive backed up our Windows 7 user folder, containing 44GB worth of files, in around 14min, which equates to a rate of 56.42 megabytes per second.

The software is set to automatically back up your specified folders every half an hour by default, but the frequency of the back up can be made daily instead and you can specify the time it should start. If the Touro is not plugged in and a scheduled back up is missed, then the backup will occur at the next scheduled time. The back up is not encrypted and it can easily be accessed by navigating through the Hitachi Backup folder on the hard drive.

A cloud backup feature is also available. Hitachi gives you 3GB of free space for this and you can specify which folders should be included, what size files should be included, and also how much bandwidth the upload should use. The cloud storage can be upgraded to 250GB for a fee.

The drive's read and write performance turned out to be very good overall. In our tests using a laptop with a fast solid state drive, the Hitachi was able to write small files from it at a rate of 59.39MBps and read them to it at a rate of 85.21MBps. Large files were written by the Hitachi at a rate of 71.25MBps and read at a rate of 100MBps, which is excellent.

If you're in the market for a new portable USB 3.0 drive, the Hitachi is well worth considering - and even if you're not in the market, you can never have too many portable hard drives lying around. It's fast and it comes with easy-to-use back up software.

Hitachi's Touro Mobile Pro Portable Drive is a fast 500GB external drive with a 7200rpm spin speed and a USB 3.0 interface. It ships with easy-to-use back up software, which is well suited to anyone who knows they should back up their data but don't know where to start.

There's no shortage of portable hard disks available these days, but the slimline design, strong performance and back-up features of Hitachi's Touro Mobile Pro make it a good choice for anyone that needs a compact drive for use with a laptop PC.

The 64GB Transcend SSD isn't super fast and it won't blow your mind. What it has going for it are two things: a small size and better data reliability due to it having no moving parts that can break if it's dropped.

The Hitachi LifeStudio Desk Plus is a 3.5in 2TB external hard drive bundled with a 4GB USB key, which connects magnetically to the front of the device. The Hitachi LifeStudio Desk Plus supports USB 2.0 connectivity and is also USB 1.1 backwards compatible. It ships with LifeStudio and Hitachi backup software (including cloud backup storage at no additional cost) and comes with a three-year warranty.
